It's been a while, but my issue with Grandstream has always been:

1) SIP interoperability & stack problems.

2) Low-end speaker phone hardware, thus bad echo cancellation and duplex 

I mainly judge phone hardware by the quality of its speakerphone, since 
I'm a very heavy user, so it may be a personal bias.  However, by that 
metric, the Cisco 79xx's and Polycoms win, and Grandstreams, Snoms and 
Aastras lose.
